You use genetic engineering to mutate part of the DNA sequence coding for an axonemal dynein in a mouse. What sort of behavior would you expect to see in the epithelial cells of this mutant mouse?

Which of the following is NOT a piece of evidence supporting the endosymbiont hypothesis?:

Demetri is a graduate student studying cell migration. Through genetic engineering, she has created a mutant neutrophil (an immune cell that does a lot of moving around) that does not make profilin protein. When she exposes both her mutant neutrophils and normal neutrophils to a chemoattractant, what do you predict she will see under a microscope?

Describe how cristae in mitochondria are maintained. 

The “highness” or “lowness” of a sound which can be represented as a frequency or a note name is [answer1]. A single note, all by itself means nothing. It is only when we add notes together that we create music. The distance between two pitches is called an [answer2]. Each group of two notes has a special name to describe that distance between them. Pitches are, of course, defined by their frequency. The idea that pitches whose frequencies are related by powers of two (e.g. 220, 440, 880) are given the same letter name. The distance between two of these notes is called an [answer3].  If we step a little further back, we’ll see and hear that those two notes are not alone. There are more notes after the second. A group of notes in succession which our minds link together when we listen and hear as a single unit is called a phrase. A phrase that stands out as the most important part of a composition is called a [answer4].
